5000mAh 4S 14.8V 50C SMART (SPMX50004S50H5)

These 14.8V 5000mAh 4S 50C Spektrum Smart LiPo batteries deliver reliable, high-power performance for RC cars and boats. Housed in an impact-resistant ABS hard case, the packs include a built-in microchip that stores unique battery parameters and health data, enabling a Spektrum Smart charger to automatically configure charging settings and monitor safety without guesswork.

Equipped with IC3 and IC5 connectors for solder-free installation, and backward compatible with EC3/EC5 systems, they’re ready to drop into most 4S setups. The Smart technology automatically discharges to a safe storage voltage after a rest period you choose (12 to 240 hours), helping extend life by protecting the cells. The integrated memory records details like capacity, C rating, cell voltages, temperature, and cycles, and it remembers the last charging rate for a quick, consistent top-up. With a 50C continuous discharge rating, these packs deliver strong, reliable power when needed.
